5.  HADEP was a political party which had been established on 11 May 1994. At the time of its dissolution on 13 March 2003 its general secretary was the second applicant, Mr Ahmet Turan Demir, who had been elected to that post in February 2003.
6.  In the general election held on 24 December 1995 HADEP received 1,171,623 votes, which represented 4.17% of the total number of votes cast. In the general election held on 18 April 1999 HADEP received 1,482,196 votes. However, as HADEP did not succeed in passing the required threshold of 10%, it was unable to be represented in the Grand National Assembly of Turkey following these two general elections (see HADEP and Others v. Turkey (dec.), no. 51292/99, 13 November 2008). In local elections held on 18 April 1999 HADEP won control of 37 municipalities. It had branches in 47 cities and in hundreds of districts. In 2002 HADEP became a member of the Socialist International.
7.  The applicants submitted that, during a National Security Council (Milli Güvenlik Kurulu) meeting held on 18 December 1996, a decision had been taken to dissolve HADEP. In support of this assertion the applicants submitted to the Court a report which, they claimed, had been adopted by the National Security Council and which had subsequently been leaked to the press. The report, which is classified 'Secret', details a number of recommendations including “the control and pursuit of HADEP by the State in order to quell its activities”. Following this decision HADEP branches had been raided and its administrators had been subjected to physical pressure. In support of this latter argument the applicants submitted to the Court two reports, detailing the physical attacks on and the killings and forced disappearances of dozens of HADEP members, some of which have been examined by the Court (see, inter alia, Tanış and Others v. Turkey, no. 65899/01, ECHR 2005–VIII).
8. On various dates criminal proceedings were brought against a number of members of HADEP who were holding executive positions within the party. Some of the proceedings were suspended while some ended in convictions. Some of them were convicted of spreading “separatist propaganda”, in breach of section 8 of the Prevention of Terrorism Act, while others were convicted of “incitement to racial hatred and hostility in society on the basis of a distinction between social classes, races or religions”, in breach of Article 312 of the Criminal Code. A number of others were convicted of lending assistance to the PKK[1] in breach of Article 169 of the Criminal Code, for making speeches, allowing hunger strikers to use HADEP premises and for possessing a number of documents prepared by PKK members in a law-firm owned by one of them[2]. Some served their prison sentences while execution of the sentences of a number of others was stayed.
9.  On 29 January 1999 the chief prosecutor at the Court of Cassation brought proceedings before the Constitutional Court and demanded that HADEP be dissolved. The chief prosecutor argued that HADEP had become a “centre of illegal activities against the integrity of Turkey”. In support of his allegations the chief prosecutor referred to the criminal proceedings pending against members of HADEP and a number of activities of its members. One incident relied on by the chief prosecutor was that during HADEP's annual general meeting in 1996 the Turkish flag had been taken down and replaced with a PKK flag.
10.  On 25 February 1999 the chief prosecutor asked the Constitutional Court to render an interim decision banning HADEP from taking part in the forthcoming April general and local elections. The chief prosecutor's request was refused by the Constitutional Court on 8 March 1999.
11.  On 5 April 1999 lawyers for HADEP submitted a written defence to the Constitutional Court. They alleged that the chief prosecutor's request for the dissolution of HADEP had been made as a result of the National Security Council's above-mentioned decision (see paragraph 7). They further argued, inter alia, that as it was not clear what the accusations against HADEP were, it was not possible for them to make full use of their defence rights. The lawyers relied on Articles 6, 9, 10, 11 and 14 of the Convention and Article 3 of Protocol No. 1 to the Convention, and asked the Constitutional Court to take into account the decisions and judgments of the European Court of Human Rights in cases concerning the dissolution of a number of other political parties in Turkey.
12.  The chief prosecutor maintained in his written submissions of 9 April 1999 that HADEP had close ties with the PKK, and alleged that the former was being controlled by the latter. The chief prosecutor also repeated his request for HADEP to be dissolved before the elections which were to be held on 18 April 1999. This request was not accepted by the Constitutional Court.
13. During the proceedings, in their submissions to the Constitutional Court HADEP's representatives drew attention to the fact that the person who had taken down the flag was not a member of the party. They further stated that, immediately after the incident the HADEP congress had publicly condemned the incident. Since then HADEP had been dissociating itself from the incident and condemning it as an attack on a common symbolic value of the people of Turkey.
14.  In its decision of 13 March 2003 the Constitutional Court decided unanimously to dissolve HADEP. The Constitutional Court based its decision on Articles 68 and 69 of the Constitution and sections 101 and 103 of the Political Parties Act (Law no. 2820). In arriving at its conclusion, the Constitutional Court took account of the activities of certain leaders and members of HADEP and concluded that HADEP had become a centre of illegal activities which included aiding and abetting the PKK.
15.  The Constitutional Court noted, in particular, that during HADEP's annual general meeting in 1996 a non-HADEP member wearing a mask had taken down the Turkish flag and replaced it with a PKK flag and a poster of the then leader of the PKK, Abdullah Öcalan. During the same meeting slogans had also been chanted in support of the PKK and its leader[3]. The then general secretary of HADEP Mr Murat Bozlak, who was present during the meeting on that day, had done nothing to stop the Turkish flag being taken down and had stated during his speech that “the existence of the Kurds in Turkey, who were not allowed to speak their mother tongue, had been denied. The PKK, despite ongoing military operations, massacres and provocations, was holding its ceasefire. Nothing could be resolved with military operations or with occupation.” The Constitutional Court considered the taking down of the Turkish flag as proof of the links between HADEP and the PKK. It further considered that the references made by Mr Bozlak to Turkey's fight against terrorism as an “occupation” and portraying Kurds as a separate nation showed that Mr Bozlak was supporting the PKK[4].
16.  The Constitutional Court referred to Article 11 of the Convention in its judgment and stated that the rights guaranteed in that provision were not absolute and could be restricted in the circumstances listed in Article 11 § 2 of the Convention. It also referred to Article 17 of the Convention, and reached the following conclusion:
“Carrying out activities, by relying on democratic rights and freedoms, against the indivisible unity of the State with its nation is unacceptable. In such circumstances it is the duty and raison d'être of the State to prevent the abuse of these rights and freedoms. Allowing a political party which supports terrorism and which is supported by terrorism to continue to exist cannot be contemplated.
In statements and speeches made on behalf of the People's Democracy Party and in the course of various meetings, the party's general secretary Murat Bozlak, other party officials and chairmen and members of the party's provincial and district branches have stated that the Kurdish nation was a different nation from the Turkish nation; that the State of the Turkish Republic had been enforcing a policy of pressure and oppression on the Kurdish nation; that there was an ongoing war between the PKK terrorist organisation and the State of the Republic of Turkey; and that the Kurdish nation should take sides with the PKK in this war. Some of these activities have resulted in convictions. These persons have thus aided and harboured the PKK and its leader Abdullah Öcalan, whose aim is to destroy the indivisible unity of the State. The incidents, which are detailed in relevant parts of this judgment and which took place during the Second Congress of the People's Democracy Party on 23 June 1996 in Ankara, as well as the objects and documents found in the party headquarters and in the party's various branches confirm the [above-mentioned conclusion].
Activities by members of the People's Democracy Party and the evidence [in our possession] clearly show the links between the respondent party and the PKK. The following incidents and activities – and many others and judgments rendered by courts – are proof of the connection and support between the People's Democracy Party and the PKK terrorist organisation:
–  organisation of various activities – under instructions from the PKK – such as hunger strikes, demonstrations and issuing press releases with a view to protesting against the attempt to assassinate Öcalan and against the work that had been carried out by the State of the Turkish Republic to apprehend Öcalan, and against his subsequent arrest;
–  work to create, by referring to concepts such as freedom, brotherhood and peace, a sense of a different nation among the people who live in a certain part of the country or who claim to belong to a certain ethnic group;
–  description of the State's struggle against the PKK terrorist organisation as a 'dirty war', as well as taking sides with the PKK in this war by carrying out certain activities and by displaying certain behaviour;
–  provision of training to a number of young people, in line with the PKK ideology but under the disguise of in-party training, with a view to recruiting them to the party first and subsequently to the PKK terrorist organisation in order for them to carry out activities on behalf of the PKK terrorist organisation and then sending them to the PKK's mountain camps as armed militants;
–  the keeping in the Party's headquarters and in its district and provincial branches, of objects, books, banners and photographs of members of the PKK as well as other PKK terrorist organisation propaganda documents for which the courts have issued confiscation orders;
–  the fact of allowing people to watch the organisation's media organ MED TV in these places for propaganda purposes; and
–  speeches and activities during HADEP's Second Congress.
In the light of the above, and in accordance with Articles 68 and 69 of the Constitution and section 101 (b) of the Political Parties Act, it is hereby decided to dissolve HADEP, which has become a centre of illegal activities against the indivisible unity of the State with its nation and which has aided and harboured the PKK terrorist organisation.
...”
17.  As an ancillary measure under Article 69 § 9 of the Constitution, the Constitutional Court banned 46 HADEP members and leaders from becoming founder members, ordinary members, leaders or auditors of any other political party for a period of five years[5]. The Constitutional Court also ordered the transfer of HADEP's property to the Treasury.
18.  The decision of the Constitutional Court became final following its publication in the Official Gazette on 19 July 2003.
